SAN D-BA'N D.

SPECIFICATION forming part of Letters Patent 'No. 228,761, dated June15,1880,

Application filed November 18, 1879.

To all whom it may concern Be it known that I, FREDRIC M. HURTLE, ofDowagiao, in the county of Cass and State of Michigan, have inventedcertain new and useful Improvements in Sand-Bands, for protectingvehicle-axles from sand and dirt, of which the following, in connectionwith the accompanying drawings, is a specification.

In the drawings, Figure lis a side elevation of an axle provided with asand-band embodying my invention. Fig. 2 is a vertical centrallongitudinal section thereof; Fig. 3, a like repthe band or protector;and Fig. 4 is an end view of the sand-band proper.

Like letters of reference indicate like parts.

My invention relates chiefly to the means employed to secure thesand-band proper to the axle removably.

It also consists in the construction and combination of the severalparts constituting the band or protector, substantially as hereinafterset forth.

A represents the axle,B the hub, and O the box. These parts may be madeand arranged together'in the usual manner.

D is an .annular disk applied rigidly to the inner end 'of the hub, andE and F are flanges projecting laterally from the edges of the saiddisk. The interior flange, E, is flaring, being larger at its outer endthan at its base, as shown, and projects much farther from the hub thandoes the flange F, as is clearly shown in Figs. 2 and 3.

I deem it preferable, but not absolutely essential, to bevel off theinner face of theflange F, as shown, thus making the said face parallel,or nearly parallel, to the outer face or perimeter of the flange E.

G is the sand-band proper. This part consists of a broad flaring ring orband, made largest at the end toward the hub, as shown.

H is an interiorrim or flange in the smaller end of the band G, and I Iare notches cut into the said flange. J is a cap or head, made in twinparts a a, and having a small flange or projection, at, extending fromitsouter edge. b b are offsets or lugs extending from the inner edge ofthe said cap or head. The lugs b I) are of such a size as to pass freelythrough the notches I I, and the adjacent edges of the parts a a are cutto fit the iron portion of the axle, which is square or polygonal nearthe inner end of the hub, where the said cap is to be applied. K is awedge for tightening the parts a a upon the axle, if necessary.

The band G is applied in the following manner: Before the hub is appliedI slip the said band over the spindle of the axle to a position near thewooden part of the axle, as represented in Figs. 1 and 2, the smallerend of the,

said band being toward the said wooden part, and the iron part of theaxle being there square or polygonal, as before stated. I then arrangethe parts a a about the square portion of the axle, and pass the cap orhead formed by them into the smaller end of the band G, turning thelatter until the lugs b I) enter the notches I I, and then giving thesaid band another or further turn until the said lugs engage the innerface of the flange H. The flangeH will then be engaged on its outer faceor surface by the flange a, and the part J is thus coupled to the band Gremovably, as is indicated in Figs. 2, 3, and 4. To fasten these partssecurely in their places upon the axle I drive the wedge K firmlybetween the axle and the parts a a, as represented in Fig. 2. vThehubmay now be applied, when, as will be perceived by reference to Figs. 2and 3, the band G will extend between the flanges E and F.

It will now be perceived from the foregoing description, and fromreference to drawings, that any sand passing the edge of the band Gwillfall upon the flange E, and that this flange, by being flaring, asshown and described, will prevent the sand falling upon it from reachingthe axle, for as that flange rotates with the hub the sand willgravitate toward the hub and be carried down or underneath the axle, andthen fall upon the inner face of the band G, and as the inner face ofthe said band also flares outwardly the sand will gravitate toward itsfree edge and fall out, it being understood that the sand will pass outthrough any space large enough for it to enter. The flange F willprevent mud from passing below the band Gr, but is only essential forthat purpose. The axle will not only thus be effectually protected fromsand and mud, but all the parts employed for that purpose may be made,applied, and removed with facility.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

l. The combination of the flaring hub-flange E, the flaring sand-band G,and the removable head J, made in separate twin parts, substantially asand for the purposes specified.

2. The combination of the annular hub-disk D, having thereon theinterior outwardly-flaring flange, E, and the exterior flange, F, thebroad outwardly-flaring axle-band G, adapted, substantially as shown anddescribed, to extend between the flanges E and F, and the removable headJ, consisting of separate twin parts, substantially as and for thepurposes specified.
